style="text-indent:25px">鈦合金自由鍛造設(shè)備的選擇：液壓機(jī)的分類。液壓機(jī)是一種利用液體靜壓力來加工金屬等制品的機(jī)械。它常用于壓制工藝和壓制成形工藝，如鍛壓、沖壓、冷擠、校直、彎曲、翻邊、薄板拉深、粉末冶金、壓裝等等。它的原理是帕斯卡定律，是利用液體壓強(qiáng)傳動(dòng)的機(jī)械。液壓機(jī)按照使用工作介質(zhì)的不同分為水壓機(jī)和油壓機(jī)。液壓機(jī)對(duì)工作介質(zhì)的基本要求是：1)有適宜的流動(dòng)性和低可壓縮性，以提高傳動(dòng)效率；2)能防銹蝕；3)有好的潤滑性能；4)易于密封；5)抗氧化，性能穩(wěn)定，長期工作而不變質(zhì)。液壓機(jī)較初用水作為工作介質(zhì)，以后改用在水中加入少量乳化油而成的乳化液，以增加潤滑性并減少銹蝕。后來出現(xiàn)了以礦物油為工作介質(zhì)的油壓機(jī)。油有良好的潤滑性、防腐蝕性和適度的粘性，有利于改善液壓機(jī)的性能。目前鈦合金在用的液壓機(jī)大多數(shù)是以油為介質(zhì)的。長沙立式擺碾機(jī)報(bào)價(jià)鍛造設(shè)備具有**的動(dòng)力機(jī)構(gòu)和電氣系統(tǒng)。</p><div

style="text-indent:25px">鍛造設(shè)備的選擇原則：在整個(gè)工作行程中設(shè)備不斷供給能量，使加載速度基本保持不變，特別適合于模鍛對(duì)變形速度敏感的特種合金；工作行程長，適于實(shí)現(xiàn)在一次行程中完成一個(gè)大變形量的鍛造工序，如擠壓和鐓粗。但模鍛液壓機(jī)的工作行程長使加載時(shí)間長，對(duì)模具磨損大和鍛件易于激冷，又為其缺點(diǎn)。中小型的模鍛液壓機(jī)主要用于模鍛鋁合金、鎂合金和銅合金鍛件。萬噸級(jí)以上的大型模鍛液壓機(jī)主要用于模鍛大型特種合金結(jié)構(gòu)件，例如，飛機(jī)的大型鋁合金結(jié)構(gòu)件、飛機(jī)的鈦合金隔框、接頭和梁以及高溫合金和鈦合金的發(fā)動(dòng)機(jī)壓氣機(jī)盤和渦輪盤等。</p><p
